. Be it known that I, DAN-IEL Hooks, citizen ofthe United States, and a resident of Instanter, in the county of Elk and *State of Pennsylvanla, have invented certaln new and. useful Improvements inEXcavating and Dredging Machines, of. which the following is a spec fication. I I

My inventionrelates to apparatus foreX cave-ting, and it consists o a certain base. frame and a carrying frame movably supported thereon and provided with guides for the frame of-a reciprocating cutter device, and for the frame of a ,movableexcavator comprising a chain of buckets, together with certain details of'construction, all as set of the same; Fig.2 is a sectional view on the working parts of the forth hereinafter and illustrated .in the...

accompanyingdrawing, in:whichj Figure: 1 is a sectional elevation of my proved apparatus, showing the mainparts including the boiler 1 and engine E, which may beofiany suitableforrn and character.

As shown, the engine E is a reciprocating, reversible steam. engine, but a motor propelled by airor gasor electricity maybe substituted wherever it is found advisable.

The carrier. frame C supportsat .one end an elevated frame structure F which supports a motor M ofany suit-able character, a steam cylinder supplied with motor -fluid, from the generator. D, by connectionstha, will be hereinafterv desoribed,, being. shown; and the said structure alsosupports a .veftically sliding frame (3;, guided etween ve re tical guides l, 1 and capable of being raised and lowered'b'y means ofiacable? passing l y cate a rum Wh ay. onrthe engine E. to; raise, and lower the, frame G.

The frame- G supports anen'dle'ss line of" carrier or excavating buckets I, and in order that the carrier belt which passes over guide pulleys 9, 9, may be maintained sufficiently taut, the frameconsists ofjside pieces each of which is divided into twoparts, one of, the

so a.; to maintain its proper relation to the cutters. By use of vertically reciprocating cutters I am enabled to effect thedesired excavation without the necessity of carrying any extended or cumbersome framework (or cutters of large dimensions) downward below the surface and in front of theelevator or excavator chain, and am thus. enabled to bring the latter in closer proximity to the cutters than 'ispracticable where rotating cutters orframes carrying cutters below the surface are employed. cutters shown also has the advantage of being readily operated by the engine or motor from above the surface; of being exceedingly simple in construction, and readily removed, repaired and replaced.

In operating upon some classes of earth, as, for instance, where it is solid and-waxy in character, it requires a great deal of power after driving a cutter downward into the material to draw the cutter outward, and in order to properly loosen the cutters after they have passed down Limpart a lateral vibration to the cutters by laterally vibrat-' ing the frame which sup orts the same, and they are thus loosened after penetrating the earth and can be raised without the adhesion which would otherwise result. Any suitable means may be employed for thus vibrating the cutter carrying frame. two eccentrics 26, 26, one mounted on the shaft 20 by which the excavator I is driven and the other similarly mounted on a shaft'20 extendin parallel to the shaftZO on the opposite si e of the frame H. Said shafts 20, 20 are. connected by a chain 20 extending the shaft 20;- The eccentrics 26 are so arranged as to swin the cutter framefirst in one direction and t en in the other. This vibration of the cutters not only has the effect before described, but also tends generally to aid in loosening the earth and facilitating the excavation.

Steam for actuating the cutter engine M issu plied through flexible ducts 30, 31, 3'1 whic are connected with a pipe 32 leading slide valve adapted to be actuated by a lever The character of As shown there are from the boiler D. The duct 30 is connected directly with the pipe 32 while the ducts 31, 31 are connected with a branch 32. The pipe 30 communicates-with the steam, chest m within which is arranged a suitable is one end of w ich is connected, through an adjustable rod lc, with the sliding cutter frame K. Cut-ofi valves 33, 34 are arranged respectively in the pipe 32 and branch 32", 7'5 and a hand lever 35 is arranged to control a valve in the pipe 32, while a similar lever 36 is adapted to actuate a valve controlling the passageof fluid to both the ducts 31, 31. By this jmeans the partsmay be so arranged that the cutters. will be automatically reciprocated for any desired length of time, or each stroke or operation thereof may be controlled by manipulation of thehand lever 36. If it is desired to have the cutters o erate automatically, the valve 34" is c osed and the-valve 33 opened. Byproperly adjusting the hand lever 35 fluid will be permitted to ass through the duct 30 to the chest m of the motor M, and when the parts are in the position shown,- the valve in said chest will cause the fluid to pass into the upper part of the motor cylinder thereby depressing the frame K andcutters L. As the frame K moves downward the lever is will be rocked to shift the valve in the chest 'm, andas the frame and cutters reach the limit of their downward movement the valve will be so moved that the fluidv ill enter below the'piston, and thereby the frame K and cutters L will be raised. This reciprocation will be continued as long as the valve controlled by the hand lever 35 is maintained in its open position.

In case it be desired that the operator control each reciprocation of the cutter frame, the valve 33-is closed and that at 34 opened. By then moving the hand lever 35 to open the valve controlled thereby and .by shifting the hand lever 36 the fluid will be alternately admitted to the ducts 31 and'31 .to reciprocate the piston in the motor M, and thereby lower and raise the frame K and cutters L.

The apparatus may be propelled from the engine .Ethrou h.the medium of suitable I gears between t e engine shaft and any of the supporting wheels B." As shown, two of the supporting-wheels have gearteeth {12, with which gear pinions 43, on a shaft 44 which is driven by beveled gears 45, from a' longitudinal shaft 46, supportedto turn in hearings on the frame A, and carrying a pinion 47 which slides on. and turns with the said shaft by means of a suitable feather thereon. This pinion 47 gears with the driving spur wheel 48 carried by the engine shaft and which may be. caused to'turn therewith, or it may be detachedflgafrom by means of a friction clutch 49, WHO
